Explanation: Martin Van Buren was one of the key figures who helped found the Democratic Party as a wing or option - coalition of Jeffersonian Republicans who supported Andrew Jackson in the run for President. The justification given by Van Buren for forming the Democratic Party as support for the presidential candidate is that political parties have become an important and desirable factor in political action. The existence of strong competition between the parties meant a constant check on those in power. Also, in order to be a candidate for any political function or office, they would have to go through party selection and thus ensure quality in terms of selecting a candidate to run for election.
